Electron Microprobe Laboratory (Cameca sx-100)

The electron microprobe is used to analyze the composition of meteorites, Lunar rocks and terrestrial samples. The electron microprobe sends an electron
beam in situ on a flat cm-size thin slab of rock to analyze a small spot of less than 1 micrometer size. It uses the generated X-rays to provide a
quantitative analysis of the major and minor chemical elements of minerals and glasses composing the sample. The electron microprobe can also produce maps
of the elements showing their distribution in the sample.
